[PHP] gzip compression verification
I've enabled gzip compression of pages on my site. The question is, how do I check the size of the page being sent to verify that the page is being compressed. Danny __ Do you Yahoo!? Yahoo!

You can always find the number of bytes delivered by looking at the log file. -- Raditha Dissanayake. - http://www.raditha.com/megaupload/upload.php Sneak past the PHP file upload limits. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Gzip compression
I'm looking at implementing Gzip compression and output buffering.
I think I have it working, but for some reason, the page isn't displayed
for 8-10 seconds.
It seems that the compressed page is sent immediately, but the browser
hangs on to it for some reason.
http://www.dvanhorn.org/Test/Index.php Compressed
http://www.dvanhorn.org/Test/Index2.php Not compressed
Here's the top level page code:
?
ob_start();
include('gzdoc.php');
?
html
head
meta http-equiv="Content-Type"
content="text/html; charset=iso-8859-1"
meta name="description" content="Web Page Status"
meta name="GENERATOR" content="Notepad"
? include("../headmeta.inc")?
titleCurrent status./title
? include ("Header.inc")?
/head
body
BODY BACKGROUND="../../Graphics/b_m.gif"
? include("Index.inc") ?
? include("../footer.inc") ?
? include("../do_webtrends.php") ?
/body
/html
?
gzdocout();
?
There are NO chars before, or after, the PHP flags.
Here is the contents of gzdoc.php.
?
ob_start();
flush();
$debug="1";
$Level="4";
function CheckCanGzip(){
$ret = "0";
global $HTTP_ENCODING;
if (headers_sent() || connection_timeout() || connection_aborted())
$ret = "0";
if (strpos($HTTP_ENCODING,'x-gzip') != false) $ret = "x-gzip";
if (strpos($HTTP_ENCODING,'gzip' ) != false) $ret = "gzip";
return $ret;
}
function GzDocOut($Level,$debug){
$ENCODING = CheckCanGzip();
if ($ENCODING){
print "\n!-- Use compress $ENCODING --\n";
$Contents = ob_get_contents();
ob_end_clean();
$Size = strlen($Contents);
$Crc = crc32($Contents);
$CContents = gzcompress($Contents,$level);
$CContents = substr($CContents, 0, strlen($CContents) - 4);
Header('Content-Encoding: '.$ENCODING);
Header('Content-Length: ' . strlen($CContents));
Header('Content-Length: ' . strlen(ob_get_length));
echo $CContents;
echo pack('V',$Crc) . pack('V',$Size);
exit;
}else{
ob_end_flush();
exit;
}
}

Re: [PHP] Gzip compression
Actually you are right, I just try it with MSIE 5.0 and there is a delay? But on Netscape 4.75 is ok. May be the way of unziping the page is different? I donno?!
